Indian Powerplus in Movies
Might be a Powerplus but we can't see enough of it.
Must be a 1918 or later PowerPlus if I look at the front fork
Buster Keaton: A Hard Act to Follow
It is an Indian - possibly a Powerplus from the late teens.
No earlier than 1917 because the 1916 model had a tool box on top of the tank.
Indian Powerplus as built from 1916 to 1922
I have looked better at the picture and it is a Powerplus as built from 1918 to 1922, until 1917 they had connecting rods for throttle and ignition controls in stead of cables like this one.
Days of Heaven
No idea, but I like it. And after seeing this, I have another reason to wish I had learned to ride a motocycle when I was a kid.

Its either a 1916 Powerplus as suggested (the only 1 year Powerplus had the tank between the frame tubes) but as it has gas lights and electric lights were available then and we can't see anything else it could be a late Hedstrom Indian.
The Banana Splits Adventure Hour
This bike is an Indian. We can't really see enough of it to be sure of the model but I guess it dates from around 1920 so could be a Powerplus. Note it has no lights - daylight patrols only I presume.
Indian, probably a Powerplus from around 1918.
Powerplus 1917 on but it could be a Standard, can't see which side the kickstart is.
The Roaring Road
1916 Indian Powerplus, the first yeaer for this model and the last year with the tool box on the tank.
Said in the movie to be a 1917 Indian. Going by what is written here: Link to "www.quickthrottle.com" it probably is too...
Yes, it is a Powerplus - note the sprung rear frame, something most other makes did not get for another 20 or 30 years.
